The son of a millionaire toy maker has re-launched his bid to boot his illegitimate half-brother out of the £14.5m family fortune.

Stuart Marcus built a multi-million pound games empire after beginning selling dolls' houses from a room above a small east London toy shop in the 1960s.

Shortly before he died, he put £14.5m worth of company shares into trust for his 'children': brothers Edward, 47, and Jonathan, 43.

But the family was thrown into turmoil amidst the revelation that Edward was not Stuart's son, but instead the product of an affair between his mother, Patricia Marcus, and lawyer Sydney Glossop.

Last year, a judge ruled that Stuart was not Edward's father, but said that the older half-sibling could still benefit from the £14.5m fortune on the basis that both brothers were meant to share it.
